Voyagers (2021) review

A bunch of ding-bat scientists (including Colin Farrell) concoct a (poorly thought out) plan to send a bunch of youngsters - like Christopher (Tye Sheridan), Sela (Lily-Rose Depp) and Zac (Fionn Whitehead) - on a one-way, multi-generational trip through outer space to find a habitable planet ... but when the kiddos, with their libidos, stop drinking the anti-boner juice they go bananas.  As with many of these space movies, there's a decent idea in there - in this case, how do you raise prospective astronauts to have no nostalgia for the Good Stuff of Earth? - that gets completely flubbed: one day off the medication that's constantly sedating them, they become (comically) homicidal and rape-y and Zac's being rejected by Sela makes him start accusing others of having some "alien" inside them (like the Salem Witch Trials, only in space).  It's a shame Farrell's benevolent patriarch's psyche doesn't get probed any more than it does: who hurt him so bad he volunteered to leave the planet forever?
